downy mildew) germinating on the leaf of
Arabidopsis thaliana (cf.
wikipedia) observed by fluorescent
microscopy. Double staining: The staining with calcofluor makes the cell walls of H. parasitica fluoresceing in blue and the staining with
aniline blue staining reveal callose deposition in a blue/yellow color. Germinated conidiospore (24h after inoculation) with a short germ tube trying to penetrate between cells of A. thaliana by doing an
appressorium surrounded by callose deposition. This is the first step of the short life cycle of H. parasitica. Français : Germination de conidiospores de Hyalo
peronospora parasitica (
Mildiou) à la surface d'une feuille d'
Arabidopsis thaliana (cf.
wikipedia) observée au
microscope optique à fluorescence. Double coloration : Le calcofluor rend les parois cellulaires de H. parasitica fluorescentes en bleu, tandis que le bleu d'
aniline permet de visualiser la déposition de callose an bleu/jaune. Conidiospore germé (24h après inoculation) avec un court tube germinatif qui essaye de pénétrer entre les cellules d' A. thaliana avec un appressorium entouré de dépositions de callose. C'est la première étape du cycle court de H. parasitica. Date: 2002. Source: Own work. Author:
